Standard Spiral Wound Gasket is suitable for sealing alteration of temperature and pressure are frequent, such as pipe,valve,pump etc. They are available in all standard flanges of sizes,such as ASME,JIS,DIN,EN.etc.
Type of Standard Spiral Wound Gasket
1.Basic Type Spiral Wound Gasket
2.Spiral Wound Gaskets with Inner Ring
3.Spiral Wound Gaskets with Outer Ring
4.Spiral Wound Gaskets with Inner and Outer Ring
Application of Standard Spiral Wound Gasket
It is suitable for sealing flange joints,manhole and handhold covers,tube covers,boilers,heat exchangers,press vessels,pumps,compressors and valves;industries such as petrochemical,pharmaceutical,shipbuilding,and food processing ,in power industries and nuclear power station.They are ideal for steam,oil,liquids,gases,acids,alkalines,various organic mediums and solvents.
ASME, JIS, DIN, EN，size as requirements
Structure of Standard Spiral Wound Gasket
1.Metal strip: the processed metal strip has good elasticity and recovery. It provides
the filler enough tensile strength.
2.Filler: this part is the main body of the gasket and different material is used in different conditions
3.Centering ring:the centering ring does not come into direct contact with contained fluid. It is normally made of carbon steel and electro plate or painted to avoid corrosion. Other materials are available on request.
4.Inner ring:inner ring is used to avoid excessive compression due to high seating stress in high pressure service and it is also used to reduce turbulence in the flange area. It is normally made of the same material as the gasket metallic strip.
